What it is
Poloxamine 704 is a synthetic block copolymer, meaning it's a large molecule made of repeating units of ethylene oxide and propylene oxide. It belongs to the poloxamine family, which are non-ionic surfactants known for being mild and low-foaming.
How it works
In a cosmetic product, Poloxamine 704 reduces the surface tension between oil and water, allowing them to blend into a stable mixture. This helps cleansers effectively remove makeup, sunscreen, and excess oil without stripping the skin's natural moisture barrier. It also helps other ingredients spread evenly across the skin.
Pros
Very gentle on skin
Poloxamine 704 is known for its low irritation potential, making it a good choice for people with sensitive skin or conditions like eczema.
Effective emulsifier
It helps oil and water mix smoothly, which improves the texture and stability of lotions and cleansers.
Cons and cautions
Synthetic origin
It is a man-made ingredient, which may not appeal to those seeking natural or organic skincare options.
Can feel slippery
Some users may find the texture of products containing Poloxamine 704 to be overly slippery or hard to rinse off completely.
Best for
- People with sensitive or easily irritated skin
